HELP ITS MY LAST QUESTION WITH STEP BY STEP
maks197457 [2]

Answer:

71

Step-by-step explanation:

This is the answer because:

1) First, add Andy's score and Janet's score in order to know how much they got in total:

  • Janet's score: 119 + 96 + 145 = 360
  • Andy's score: 127 + 74 + 88 = 289

2) In order to find how much more Janet scored, jus subtract Andy's score from Janet's score:

  • 360 - 289 = 71

Therefore, the answer is 71.

Hope this helps! :)

Hope made 3 different yo-yo's. She used 1 3/4 meters of string for the first yo-yo, 1 meter of string
Nat2105 [25]

Answer:

See explanation

Step-by-step explanation:

Your question is different from the attachment

Statement 1

1 adult + 5 Children

$4 for adult and total of $16 for both adult and children

Let

Cost of children skating = x

The equation is

4 + 5x = 16

Statement 2:

Cost of making a bike bag= $4

Selling price of the bike bag = $5

Profit = $16

Let x = number of bike bag

Profit = selling price - cost price

16 = 5x - 4x

16 = x(5 - 4)

Also written as

(5 - 4)x = 16

Statement 3:

Initial temperature = 16°C

Change in temperature per hour = 4°C

Final temperature = 5°C

Let

x = number of hours it changes

16 - 4x = 5

Hope made 3 different yo-yos. She used 1 3/4 meters of string for the first yo-yo, 1 meter of string for the second yo-yo, and a total of meters of string 4 1/3

length of first yo-yo = 1 3/4

length of second yo-yo = 1

Length of third yo-yo = x

Total = 4 1/3

Total length = length of first yo-yo + length of second yo-yo + length of third yo-yo

4 1/3 = 1 3/4 + 1 + x

4 1/3 = 2 3/4 + x

4 1/3 - 2 3/4 = x

13/3 - 11/4 = x

(52-33) / 12 = x

19/12 = x

x = 1 7/12

Solve by taking the square root I need help understanding steps this is hard for me. ​
Shalnov [3]

Answer:

x= -2 \pm \sqrt{13}

Step-by-step explanation:

Given: 3x^{2} -12x+27= 0

This is a quadratic equation.

3x^{2} -12x+27= 0

Taking common 3 from the equation given

⇒ 3(x^{2} -4x+9)=0

dividing both side by 3

⇒ x^{2} -4x+9=0

By using different factor, we can observe this trinomial can not be factored.

∴ solving it by completing the square.

⇒ x^{2} -4x+9=0

adding 9 on both side

⇒ x^{2} -4x= 9

To get a perfect square number as coeffecient of x is 4, lets add both side by 4.

⇒x^{2} -4x+4= 13

we know, (x+2)^{2} = x^{2} +2\times x\times 2+2^{2}

∴ (x+2)^{2} =13

Taking Square root on both side, remember; √a²= a

⇒ (x+2)= \sqrt{13}

opening parenthesis

⇒ x+2= \sqrt{13}

subtracting both side by 2

∴ x= -2 \pm \sqrt{13}
